Li'wis'SHArnm and ALFRED Snarfer.. citizens of the United States. residing at Duryea. in the county of Luzerne and State of Pennsylvania. have invented certain new and useful Irnprove-` ments in Minette' Combination" Tamping- Tools. &c.: and we do herebyv declare the following to be a full. clear. and exact descriptionof the invention. such as will enable others skilled in the art to which it appertains,` to make and uc the Same. reference being had to the accompanying drawings. and to the letters and figuresv 0f reference marked thereon. which form a part ofthis Specification Thi: invention relates to new and useful improvements in combination miners tool. adapted especially for u.-e in tamping. removing the material loosened bv the drill, etc.. and .'ompriees a Simple and efficient device of this nature having varioue details of construction and combinations' and arrangements of parts which will be hereinafter fully described. shown in the accompanying drawings and :hen epecificallv defined in the appended claim.

'e illustrate our invention in the accompanying drawings. in which 1.- l

Figure 1 is a side view of our improved tarnping tool having adjustable handle. Fig. 2 isl a longitudinal sectional view through the same. tail view of the tamping head. made pre-fen ably of wood. Fig. 4 is a detail view of a scraper attachment. and Fig. 5 a'detail view of a trimming tool. V

Reference now being had to the details of the drawings by letter, A designatesa tubu lar section of the handle which may be uare or circular7 as may be desired. provided with an aperture B therein. A rod vor tube C telescopes within the section A and is provided with apertures for the reception of the pin E which pases through apertures in the two sections and is adapted to hold the parte in adjusted relation, one

with the other. The end of the telescoping Section C is threaded :ie at C for the 're-Y oeption of the union H which has threaded Fig-5 is an enlarged dei Specicatinn of Letten Patent.

connection therewith and which union also has a contracted end interiorly threaded for engagement with the threads I upon the socket member K. in which the tamping head X is fastened. Said ramping head, which is made preferably of wood, has a flaring tamping end whichie4 grooved'on its circiunference. as at O', to allow the fuse to pass therethrough. i

In Fig. 4 of the drawings, we have shown a semicylindrical trimming* tool. designated b v letter T. and which is adapted to be oonnected to said union and provided for the purpose of trimming outthe hole made by the drill and, in 5, is illustrated a scraper T' which may also be attached to 'the section C for removing the material therein. may be tamped hy the wodden head which is attached to one of the telescoping sections. the fuse pasingA through the groove or channel.

By the provision of a tampi I head made as shown and described, the likelihood of accident incident to tamping the high explosive is reduced to a minimum and, by the provision of the detachable tofls to be connected to the inner tc1'escoping Section.'an all around convenient tool is a'orded for miners use. The sections telescop ing one within the other aord means as a measuring tool in determining the depth of the hole drilled and also n's a meansfor determining the heightA at which it is desired to form props for supporting the roof of the..

mine.
